Optimization and stochastic network theory have been successful in designing architectures for fair resource allocation to meet long-term throughput demands.  However, strict per-packet delay deadlines were not considered in this framework previously. In this talk, we propose a model for incorporating the requirements of packets with deadlines in the optimization framework.  The solution to the problem results in a joint congestion control and scheduling algorithm, which fairly allocates resources to meet the fairness objectives of both elastic and inelastic flows, and per-packet delay requirements of inelastic flows.


Juan Jose Jaramillo received his B.S. degree (summa cum laude) from Universidad Pontificia Bolivariana, Colombia, in 1998, his M.S. and Ph.D. degrees from the University of Illinois at Urbana-Champaign in 2005 and 2010, respectively, all in electrical engineering. He is the recipient of a Fulbright fellowship. From 1999 to 2003 he worked at Empresas Publicas de Medellin in Colombia. He is currently with Iowa State University, where he is a Postdoctoral Research Associate at the Department of Electrical and Computer Engineering. His research interests include communication networks and game theory.
